Be it known that I, WILLIAM U. Gm rir'rrrs, acitizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State fof Pennsylvania, have inventedcertain new'fandqusjei ul 1mprovements in 3 ValveActuating Mechanism for ater: Closet, Apparatus, of h which following is a specification. 10 flush tanks, for flushing water closet hoppers and the like, and hasfor its object to provide an improved means for positively and'efiectively controllin'g'the operation of the discharge valve of the flush tank.

A further object of my invention is to provide an apparatus which is simple in construction, effective in operation and par- I ticularly adapted for positive action.

In the accompanying drawinglhave illustrated one formof a convenient embodiment of my invention, but it will be understood that changes in the details of? construction,

may be made within the scope of the claim without departing from the same.

In the drawing, 1 have shown a water closet apparatus embodying my invention, the flush tank and a portion of the adjacent mechanism being shown in vertical longitudinal section, while other adjuncts of the mechanism are shown in side elevation.

Referring to the drawing, 1 designates a water closet hopper or bowl, and 2a valve mechanism for controlling the flow of water 1 from a suitable source of supply through a pipe 3 to the flush tank. The valve mechanism as here shown is controlled by means of a rod 5 slidingly mounted in a suitable support or hearing and adapted to be operated by the means of the movement of the seat 6 which it will be understoodis pivoted at 7, and when depressed strikes the end of the rod 5 and causes the valve to be opened to supply water to the tank 4. The seat 6 is normally held in raised position, as shown in the drawings, by means of a weighted arm orlever 8, which, as will be readily apparent,is so arranged as to maintain the seat 6 in elevated position as shown. 9 designates an arm suitably fixed in any desired manner to the seat 6 and depending there from so as to normally extend downwardly into the mouth of the bowl 1 where it is adapted, when the seat is depressed, to con- ,55 tact withthe end of the rod 10 which is L slidingly mounted in a spider bushing .11 Se- My invention relates to improvements in curedinthe fiushf delivery pipe 12.

the flush tank 4 and through the discharge port 20. The lower end oftherod 17 passes through a hole in a cross piece17 by which it is held and guided in its movements. It will be noted that the pipe 18 is preferably providedwith an extension 21 forthepun pose of receivingthe valve member 22 which I is fixed to the end of the rod 17 and isadapted to close the opening 20 at certain times.

Particular attention is directedflto thei novel toggle'mechanism interposed between the, valve rod and the operating rod controlled by the movement of the seat 6, since this is an important feature of my invention,

and serves as a positive means to control the movement of the valve 22 and also magnifies the movement of the rod 10 in order to insure the opening of the valve 22. at the desired time. I

The operation may be described as follows: When the seat 6 is depressed, it contacts with the upper end ofthe rod 5 so that the valve or valves in the mechanism 2 are opened to permit water to flow into the tank l and fill the same.

the arm 9 has been brought Simultaneous with this operation, into contact with the rod 10, thereby shifting the latter, and through the toggle connections above described, raise the rod 17,

and consequently close the valve 22 so that. the water entering the flush tank 4 may not escape until the said tank is filled or partially filled. As soon as the seat6 is re leased, the weight .8 causes it to return to the position shown in the drawing, thereby.

closing the valve mechanism 2, to cut off the supply of water, and as the rod 10 is relieved from pressure on the arm 9, the

weight of therod 17 with its adjuncts causes the parts to lower, thus opening the valve 22 and allowing the tank 4i to discharge in h r the usual manner.
